Answer:

The large sample n = 1713.96

Step-by-step explanation:

<u>Explanation</u>:-

given the population proportion was estimated to be 0.22

population proportion (P) = 0.22

The 95 % level of significance = 1.96≅ 2

The margin of  error = 0.02

The formula of margin error

                                   \frac{2\sqrt{p(1-p)} }{\sqrt{n} } = 0.02    …  ( i )

Substitute 'p' values in equation (1)

\frac{2\sqrt{0.22(1-0.22)} }{\sqrt{n} } = 0.02

cross multiplication and simplification, we get

2X0.414= 0.02 \sqrt{n}

\frac{2X0.414}{0.02} = \sqrt{n}

41.4 = \sqrt{n}

squaring on both sides, we get

the large sample n = 1713.96

The number of State Parks in California is 36 more than one third the number of State Parks in Florida. There are 85 State Parks
Ronch [10]

Answer:

you would set it up as (85 - 36) * 3 = x

Step-by-step explanation:

you need to subtract 36 from 85 to get 49, then multiply it by 3 to get 147 because since the amount of state parks in cali is 36 more than 1/3 of the state parks in florida, you would do the opposite operations to figure out how many state parks florida has.
